Extract the latest CVS into the MediaPortal folder and overwrite old files

Execute the 'start.bat' file to (re)register any new modules

Redo your entire configuration

(This is somewhat clumbersome, but it will avoid any weird crashes reported by some users)

Corrupt/Missing fonts can lead to unexpected crashes in Configuration.exe

Note by infinityloop:

If the MPSA.ax has been changed in a cvs-snapshot, re-registering is neccessary.
The fast way is to use the start.bat after you have extracted the CVS-Snapshot into your MediaPortal folder.
The save way is to do it manualy.

Re-Registering MPSA.ax

Start -> run -> cmd

Unregistering old MPSA.ax :regsvr32 -u d:/MediaPortal/MPSA.ax

Registering MPSA.ax :regsvr32 d:/MediaPortal/MPSA.ax
You have to enter the correct Path to your MediaPortal installation!
